Q.1 (i) A yeast artificial chromosome (short YAC) is a vector used to clone large DNA fragments (larger than 100 kb and up to 3000 kb). It is an artificially constructed chromosome and contains the telomeric, centromeric, and replication origin sequences needed for replication and preservation in yeast cells. Built using an initial circular plasmid, they are linearised by using restriction enzymes, and then DNA ligase can add a sequence or gene of interest within the linear molecule by the use of cohesive ends. They were first described in 1983 by Murray & Szostak.

Cassia fistula belonging to Leguminosae family, is widely used for its medicinal properties, its main property being that of a mild laxative suitable for children and pregnant women. It is also a purgative due to the wax aloin and a tonic (Satyavati and Sharma, 1989) and has been reported to treat many other intestinal disorders like healing ulcers (Biswas et al., 1973; Kirtikar and Basu, 1975). The plant has a high therapeutic value and it exerts an antipyretic and analgesic effect (Patel et al., 1965). Besides, it has been found to exhibit antinflammatory and hypoglycaemic activity (Datta and Kumar, 1985).
